In this paper, we focus on uninorms with non-trivial unit on bounded lattices. Based on the existence a t-norm T acting on [0, e] as well as a t-conorm S acting on [e, 1], we present some construction methods for uninorms on a bounded lattice, where some additional conditions on the bounded lattice and the neutral element e are required. The role of these additional conditions is emphasized. Finally, we present some results and some illustrative examples derived from these methods.
